The ultrafine polyester draw textured yarns and the method for processing are characterized in that the specification 20D/144F is adopted, circular blow and a POY (partially oriented yarn)-DTY (draw textured yarn) two-step process line are adopted for production. The method is reasonable, the fibers are fine in spinnability and excellent in physical indexes, broken ends of filaments are few, conversion success rate is high, dyeing uniformity can reach more than 99%, and full bobbin rate can reach more than 98%. The ultrafine polyester draw textured yarns are smooth in weaving, fabrics made of the ultrafine polyester draw textured yarns are light and soft and have good style, weaving requirements of high-grade apparel fabrics are met, and the grade and added values of products are improved.
Description
Technical field
The present invention relates to a kind of synthetic fiber and processing method thereof, specifically is a kind of 20D/144F super fine polyester low-stretch yarn and processing method thereof.
Background technology
Terylene is as one of the big main force of three in synthetic fiber fiber, because of its good physics and chemical characteristic are widely used in garment material and other non-garment industry.The terylen product since coming out, also once with its drapability is good, intensity is high, well-pressed, be difficult for becoming and be used as main textile raw material by downstream user and weave all kinds of textiless.Along with economic globalization, the market internationalization, people are also increasingly high to the requirement of clothes; Not only to have comfortableness; Also will have functionally, lining just develops to light, gentle, functional direction, and composite fibre materials just need improve constantly performance and satisfy requirements of weaving process.Superfine fibre is because its high spreadability, superperformance such as soft, comfortable and easy to wear have become a focus textile raw material of each weaving manufacturing enterprise exploitation grade textiles both at home and abroad, and its use can effectively improve the class and the added value of product.In addition, superfine fibre also can be applicable to such as other fields such as heat-insulating material, filtering material, ion exchange material, imbibition material, biologic applications.The combination in and other technologies field differential through superfine fibre, Application Areas from now on is with increasingly extensive.
Superfine fibre product development difficulty, the product of production is relatively poor aspect physical indexs such as bar evenness, dyeability, and full-rolling rate and AA level rate are lower, influence weaving of product, can not improve the class and the added value of product.To the above difficulty that the exploitation superfine fibre exists, we have developed a kind of high-quality superfine fibre, have excellent physical index, can satisfy the requirements of weaving process of high-grade fabric, have promoted the class and the added value of product.
Summary of the invention
The purpose of this invention is to provide a kind of 20D/144F super fine polyester low-stretch yarn and processing method thereof, make the superfine fibre of production have excellent physical index, can satisfy the requirements of weaving process of high-grade fabric, promoted the class and the added value of product.
The object of the invention is realized through following technical scheme:
A kind of super fine polyester low-stretch yarn, the fused mass directly spinning technology is produced, and adopts ring blowing cooling technology and POY-DTY two-step process route to produce, and it is characterized in that specification is 20D/144F, excellent product performance.
A kind of processing method of super fine polyester low-stretch yarn; Carry out esterification by raw material p-phthalic acid and ethylene glycol; Gather the preparation polyester fondant through precondensation and final minification again and carry out direct fabrics, employing spinning-false twisting two-step process route, the viscosity of prepared polyester fondant is 0.650;
Production process route is: polyester fondant → melt Conveying → spinning manifold → measuring pump → assembly → lateral blowing cooling → boundling oils → path → in advance network → first draw-off godet → master network → second spinning reel → coilings → POY → original silk rack → the cut hot case → coldplate of a device → first roller → twist arrester → first → false twister → second roller → Network device → auxiliary roller → second hot case → the 3rd roller → spy thread device → roller → coiling → DTY oils
It is characterized in that technological parameter is:
POY：

2. spinnerets: PRB-88-144-0.10*0.20, metal sand proportioning 100-120 order: 180 μ m/g, component pressure are 190bar;
3. encircle blow pressure 700pa, 23 ℃ of temperature, humidity 85%, zone of silence height 60mm, EVO pressure reduction 18pa;
4. the valid density of finish is 88%, the rate of oiling is 0.40%, oily frame height 500mm;
5. winding speed is 2500m/min; The speed of first draw-off godet is 2540m/min, and the speed of second spinning reel is 2530m/min, before Network device is positioned at second spinning reel; Network pressure is 1bar; The coiling start angle is that 4.9 °, handoff angle are 5 °, and initial contact pressure is 90N, and it is good to guarantee that the terylene pre-oriented fiber spinning cake is shaped;
DTY：
Adopt 1-5-1 polyurethane friction plate combination technique to think that the speed of 500m/min adds bullet, draw ratio is that the temperature of 1.65, the first hot casees is 182 ℃, and the temperature of the second hot case is 145 ℃, and network pressure air is 1.4Kg/cm
